Zeno of Citium
334–262 BCE
Zeno was a merchant who, while on a voyage from his hometown in modern-day Cyprus to Greece, was supposedly shipwrecked and lost everything he owned. Distraught, he found himself seeking answers that would help him cope with life whereupon he visited a bookshop in search for philosophers from whom to learn and was directed to Crates the Cynic.
Besides studying under Crates, Zeno was also a voracious reader of Socrates, Plato’s Academy and the Megarian School. Elements of these schools, especially in the form of responses to and improvements over their teachings, are visible all through Stoicism, such as in the idea of Preferred indifferents in response to Cynicism and Epicureanism.
NB Not to be confused with the pre-Socratic philosopher Zeno of Elea.
